Manchester United must beware of signing out-of-favour Real Madrid star James Rodriguez.
The Colombian, who could be part of a mass exodus at the Bernabeu this summer, is reportedly on the Red Devils' radar and could be available for some £60 million.
However, despite scoring the most goals at the 2014 World Cup in Brazil, Rodriguez lacks the ability to play at the highest level having endured a difficult spell since arriving in Madrid from Monaco.

Following Angel Di Maria's departure in 2014, Rodriguez was signed in the hope that he could help Cristiano Ronaldo and co. defend their Champions League title.
The 24-year-old's stellar showings in Brazil catapulted his value and, despite joining Monaco from Portugal's Porto the previous year, Rodriguez fetched a huge fee to make him the fourth most expensive player of all time behind Gareth Bale, Ronaldo and Luis Suarez.

Many believed him to be the ideal replacement for the outgoing Di Maria, yet the Colombia international has struggled under Carlo Ancelotti, Rafa Benitez and now Zinedine Zidane in the Spanish capital.
With United failing to mount a Premier League title challenge for the third season running, manager Louis van Gaal could leave this summer with the common consensus being that Jose Mourinho will replace the Dutchman.
And Rodriguez is reportedly amongst the Portuguese's top targets. For too long the club's transfer policy has yielded little reward and more stardust is needed to help them return to the top of English football.
Zidane apparently harbours doubts over Rodriguez, along with fan favourite Isco, and the duo could be available following a difficult season at the Bernabeu until recently.
Di Maria and Radamel Falcao both arrived at United billed to eradicate any memories of the disastrous David Moyes era yet neither stayed longer than a year, with the former now at Paris Saint-Germain and Falcao failing to make an impression at Chelsea.
United cannot afford any passengers, particularly if Van Gaal leaves and Mourinho comes in. The club already have Wayne Rooney, Juan Mata and Jesse Lingard capable of playing behind the striker, meaning Rodriguez could represent something of an expensive luxury.
Big money transfers have failed at Old Trafford in the past, suggesting the 20-time league winners must steer clear of Rodriguez and instead focus on plugging gaps elsewhere and developing their exciting crop of youngsters.
